Re: Matching tyres to frame.

Moulton suspension. Big spring in the head-tube, so the front wheel is suspended. The whole thing is damped by the linkages that are tightened a little bit.Front Forks.jpegThe front bit with the brake on, goes up and down inside the head-tube. The rear bit is the steering unit connected directly to...

Re: Matching tyres to frame.

Tyres are more akin to the suspension springs on a car than the dampers as they have very little in the way of damping properties. Gatorskins have a very stiff carcass so don't flex well. Not the best of tyres IMO for a good ride quality. As to the debate about the ride quality of steel vs ally, car...

Re: New tyres

Are you sure they're not 26x1 1/4, 32-597?

Re: Old Racer

I think it could be a Falcon Professional circa '82. Measure the seat post. If it is a Falcon Pro it will measure 27.0mm whereas if it's the more common Reynolds 531 as on the Dawes it will measure 27.2mm

EDIT: Looking at the frame number the format is correct for Dawes so that is probably correct.

Re: Upgrade 11-28 to 11-32

I have a bike running a short cage Ultegra rear mech with a 32 at the back paired to a 50/34 chainset. It works but requires careful setting up particularly with regard to the chain length. The chain needs to be as short as you can get away with whilst still being able to run from large chainring to...

Re: Gear ratios, in inches

If it's flat, it's 100 inches or even more. Relax and take your time. There's not much flat round here, but there is a flat bit, I sit in 100+ for half a mile or so. If it was further, I'd carry on relaxing. I feel for your chains and knees :shock: Seriously even when I was young and fit a gear of ...

Re: Disc Brake Pads

Goto disco brakes. Review their categorisation of the range of pads they sell. Choose the best match for your needs. I was quite happy with the Kevlar or copper free pads. That's very helpful. The Copper Free pads look interesting as they are amongst the most powerful with good heat dissipation and...

Thanks. I should have stated that I'm using Spyres, so cable operated and no plastic.

Disc Brake Pads

I need to buy a spare set of brake pads for the rear disc brake on our tandem. Obviously it works harder than on a solo bike so what is the best sort of compound to go for? My experience with motorcycles would push me towards sintered pads and up until recently I've only used rim or drum brake on pe...

Re: Exploding Inner Tube

On a not so funny note I had a customer who was a really hard rider. He used to ride everywhere flat out. Whenever he came into the shop he would be standing in a pool of sweat within a couple of minutes. He wouldn't think twice about riding non-stop from London to Liverpool to visit his family - yo...

Re: Exploding Inner Tube

When I had a bike shop this was a fairly common occurrence. A new bike would be serviced, including inflating the tyres, and put on display. Some time later an enormous explosion would be heard and a search was made for the offending bike. Clearly tyres were often badly fitted when the bikes were as...

Re: Gears: are 3x setups extinct?

I've always found with triples you end up spending almost all the time either in the big or the little chainring. For most needs, a double suffices and the extra complication of a triple isn't needed, particularly as modern cassettes have such wide ranges. Where a triple comes into its own is when ...

Re: Which work spd shoes - 3000 miles per year?

These are not leather but are comfortable off the bike and I think very presentable.

Re: Another seized-seatpost question

My experience is that an alloy post corroded in a steel frame will be chemically bonded and neither gentle heat nor the application of release oil will have any positive effect. As suggested above, careful use of a hacksaw blade to cut a couple of slots and chiselling the post away from the frame wi...
